Introduction

Rectangular connectors are designed to link two components electrically, allowing them to be separated and reconnected quickly and easily. This article will focus on the SFM-140-L2-H-D, an rectangular connector specifically adapted for harsh environment applications. In addition, the article will discuss the application field and working principle of this connector.

Application Field

The SFM-140-L2-H-D is designed for use in harsh environment applications. The connector is ideal for applications that require a reliable connection in outdoor and/or wet areas such as, off-highway vehicles, and agricultural and construction equipment, communication, and industrial automation systems.The SFM-140-L2-H-D is an IP67 rated connector. This indicates that it has a very good dust- and water-tightness protection rating. This rating is achieved through the use of an advanced, two-part shell which incorporates an O-ring seal and a dust cap. The connector is designed to be insert-resistant which means that it cannot be removed from a device without the help of a special tool. This feature makes it ideal for rugged applications which may be subject to vibration and shock.The SFM-140-L2-H-D is designed with a thermoplastic dielectric insulator and a unique 3 contact contact design which provides lasting performance and resistance to vibration and corrosion. The contact design ensures that the connection is not compromised by loosening or misalignment over time. The connector also has a secure locking system which requires a simple key release operation to remove the connector from the mating device.

Working Principle

The working principle of the SFM-140-L2-H-D is based on the electrical conductivity of two metals. When two metals are in close contact and the voltage is applied, a small electric current is created, which then carries a signal. Change in the voltage or current will affect the flow of the signal.The SFM-140-L2-H-D connector is designed with a thermoplastic dielectric insulator which isolates the two contacts. The dielectric insulator eliminates any conductivity between the two contacts and prevents connection failure due to vibrations. The unique 3 contact design helps to ensure that the connection is not compromised by loosening or misalignment over time.The connector also provides good shielding against EMI/RFI (electromagnetic interference and radio frequency interference) which can affect the signal quality. The connector is also designed to be resistant to corrosion and environmental factors such as humidity and temperature.

Conclusion

The SFM-140-L2-H-D is a rugged rectangular connector designed for harsh environment applications. The connector is IP67 rated and provides good shielding against EMI/RFI. The unique 3 contact design provides lasting performance and resistance to vibration and corrosion. The connection system is also secure and requires a simple key release operation to remove the connector from the mating device.
